AI Technical Summary

Benefits of technology

This technology allows for securely transmitting sensitive data without being triggered too frequently due to an external factor like distance from another person's phone (NFC). It uses specialized hardware that captures signals emitted during this process with certain timing intervals. By analyzing these captured signal patterns, we aimed at finding ways to prevent unauthorised accesses while still ensuring their accuracy was achieved through specific triggers.

Problems solved by technology

The technical problem addressed in this patented text relates how to prevent accidental or incorrect triggers on certain types of wireless devices used with proximity-based technologies like radiofrequency identification (RFID).

Embodiment Construction

[0036] The present invention will be further described in detail with reference to the accompanying drawings and embodiments.

[0037] The embodiment of the present invention provides an NFC trigger method, such as figure 1 As shown, the method includes:

[0038] Step 101: when an NFC tag is sensed, obtain the first sensing moment when the NFC tag is sensed;

[0039] Step 102: Obtain the writing time and the preset delay triggering time when the NFC tag completes writing data;

[0040] Step 103: judging whether the difference between the first sensing moment and the writing moment is greater than the delay trigger duration;

[0041] Step 104: When the difference between the first sensing moment and the writing moment is greater than the delay trigger time, acquire and execute the instruction in the NFC tag.

[0042] Specifically, NFC (Near Field Communication, referred to as NFC) is a fast short-distance high-frequency communication technology that works at a frequency of 13.5

Abstract

The invention discloses a near field communication triggering method and device, electronic equipment and a storage medium. The method comprises the following steps of when a near field communication tag is sensed, acquiring a first sensing moment when the near field communication tag is sensed, acquiring a write-in moment when the near field communication tag completes data write-in and a preset delay trigger duration, judging whether the difference value between the first sensing moment and the write-in moment is greater than the delay trigger duration or not, and when the difference value between the first sensing moment and the write-in moment is greater than the delay trigger duration, acquiring and executing an instruction in the near field communication tag. By adopting the scheme provided by the invention, the near field communication trigger sensitivity can be reduced, and the near field communication trigger safety can be improved.
